Wireless communication method, terminal device, and network device Technical Field

[0001] The present application relates to the field of communication technology, and more specifically, to a wireless communication method, terminal equipment, and network equipment. Background Art

[0002] Some communication technologies introduce a first receiver (e.g., a low power-wake up receiver (LP-WUR)) in a terminal device. While the first receiver is monitoring a first signal (e.g., a low power-wake up signal (LP-WUS)), a second receiver (e.g., a main receiver (MR)) may be in a low power state. The first signal may be used to wake up the second receiver. For example, upon receiving the first signal, the first receiver may wake up the second receiver. Since the second receiver may be in a low power state, this solution may save energy consumption of the second receiver.

[0047] It should be understood that all or part of the functions of the communication device in this application can also be implemented through software functions running on hardware, or through virtualization functions instantiated on a platform (such as a cloud platform).

[0048] Discontinuous reception (DRX)

[0049] To reduce terminal power consumption, some communication systems (such as LTE and NR systems) have introduced the DRX mechanism. The DRX mechanism eliminates the need for terminals to keep their receivers powered on when not receiving data, instead enabling them to enter a discontinuous reception state, thereby saving power. The DRX mechanism involves configuring a DRX cycle for the terminal. A DRX cycle consists of an "on duration" and an "opportunity for DRX." During the on duration, the terminal monitors and receives downlink channels and signals, including the PDCCH. During the inactivity period, the terminal does not receive downlink channels and signals, such as the PDCCH, to reduce power consumption.

[0050] The evolution of communication systems has placed higher demands on terminal energy conservation. For some DRX mechanisms, during each activation period, terminals must continuously monitor the PDCCH to determine whether the network equipment is scheduling data for them. However, for most terminals, there may be long periods without the need to receive data, yet they still need to periodically wake up to monitor for possible downlink transmissions. There is room for further optimization of energy conservation methods for these terminals.

[0051] To address the above issues, energy-saving signals have been introduced in some communication standards (such as the 3GPP R16 standard). Energy-saving signals can achieve further energy saving for terminal devices in the radio resource control (RRC) connected state (RRC_CONNECTED). Energy-saving signals can be used in conjunction with the DRX mechanism. For example, before entering the DRX activation period, the terminal can first determine whether it needs to receive data during the DRX activation period based on the indication of the energy-saving signal. When the terminal has data to transmit in a DRX cycle, the energy-saving signal "wakes up" the terminal, and accordingly, the terminal monitors the PDCCH during the DRX activation period. Conversely, when the terminal has no data to transmit in a DRX cycle, the energy-saving signal does not "wake up" the terminal, and accordingly, the terminal does not need to monitor the PDCCH during the DRX activation period. This DRX mechanism combined with energy-saving signals, if the energy-saving signal does not wake up the terminal in a DRX cycle, the terminal does not need to monitor the PDCCH even if it is in the DRX activation period, thereby achieving energy saving.

[0052] Some communication standards, such as 3GPP Release 17, have further established a Terminal Energy Saving Enhancement Project. This project further standardizes energy saving for terminals in the RRC Idle (RRC_IDLE) and RRC Deactivated (RRC_INACTIVE) states. Power consumption for terminals in the RRC_IDLE and RRC_INACTIVE states primarily stems from periodic discontinuous reception (DP) paging, including time-frequency synchronization recovery and automatic gain control (AGC) before the PO arrives, as well as power consumption during DP detection of the PDCCH.

[0053] To reduce power consumption during paging, relevant standards introduce a power-saving signal for paging reception. This power-saving signal can be called a PEI. The PEI can be used to indicate whether a terminal needs to receive a paging call before its PO arrives. In other words, the PEI can be used to indicate whether to "wake up" the terminal before its PO arrives.

[0054] PEI

[0055] The following uses the PEI design in the 3GPP R17 standard as an example to illustrate PEI-related technologies.

[0056] PEI occasion (PEI-O)

[0057] PEI-O is a collection of multiple physical downlink control channel (PDCCH) monitoring opportunities.

[0058] In some embodiments, when nrofPDCCH-MonitoringOccasionPerSSB-InPO is not configured, PEI-O can be a set of S consecutive PDCCH monitoring occasions. Where S is the number of actual transmitted SSBs determined by ssb-PositionsInBurst in system information broadcast 1 (SIB1). In PEI-O, the quasi co-location (QCL) of the Kth PEI PDCCH monitoring occasion can be the same as the Kth PDCCH monitoring occasion paged in PO (the reference of the QCL is the SSB).

[0059] In unlicensed spectrum, PEI-O can be a set of (S*X) consecutive PDCCH monitoring opportunities. Among them, S is the number of actual transmitted SSBs determined according to ssb-PositionsInBurst in SIB1. If nrofPDCCH-MonitoringOccasionPerSSB-InPO is configured, X takes the configured value, otherwise X=1. The (x*S+K)th PDCCH monitoring opportunity in the PEI monitoring opportunity corresponds to the Kth SSB transmitted, where x=0, 1, ..., X-1, K=1, 2..., S. If X>1, when the terminal detects a PEI in the PEI monitoring opportunity, the terminal does not need to continue to monitor the subsequent monitoring opportunities associated with the PEI monitoring opportunity.

[0060] Mapping of PEI and PO

[0061] Network equipment can configure multiple POs for each paging frame (PF). On the one hand, if each PEI corresponds to a PO, there will be a large number of independent PEIs, which will increase the PEI overhead. On the other hand, if each PEI corresponds to a PO, the PEIs corresponding to these POs may overlap in the time domain. In the 3GPP R15 / 16 standard, a wake-up signal (WUS) can be associated with one PO or multiple POs. When designing PEI, in order to reduce PEI overhead and avoid PEI overlap, a mapping mechanism similar to the WUS in the 3GPP R15 / 16 standard was finally determined, that is, one PEI can be associated with one PO or multiple POs.

[0062] In some embodiments, one PEI can be associated with POnumPerPEI POs. As shown in FIG2 , POnumPerPEI can be 4. That is, in FIG2 , one PEI can be associated with 4 POs.

[0063] Optionally, the POnumPerPEI POs associated with a PEI may be in one or more PFs, and the maximum number of PFs associated with a PEI is 2.

[0064] Optionally, POnumPerPEI is N×N s Where N is the number of paging frames in a paging cycle, N s It can be the number of POs in a paging frame. POnumPerPEI can be configured through SIB and its value range can be {1, 2, 4, 8}.

[0065] Location of PEI-O

[0066] The terminal can determine the position of the PO corresponding to the PEI-O based on the reference point and the offset value (from the reference point to the first PDCCH monitoring opportunity of the PEI-O). The following is an example with reference to Figure 2. The position of the PEI-O can be determined through steps 1 and 2.

[0067] Step 1: Determine the reference frame and use the starting point of the reference frame as the reference point.

[0068] The reference frame can be determined based on the first PF among all PFs associated with the PEI (when a PEI is associated with multiple POs, the associated POs may be located in different PFs) and a frame-level offset value.

[0069] The frame-level offset value from the first PF among all PFs associated with the PEI to the reference frame can be configured through the SIB.

[0070] Step 2: Determine the position of the first PDCCH monitoring opportunity in PEI-O based on the reference point and the symbol-level offset value.

[0071] The symbol-level offset value from the reference point to the first PDCCH monitoring opportunity in PEI-O may be configured through SIB. For example, the symbol-level offset value may be provided by firstPDCCH-MonitoringOccasionOfPEI-O.

[0072] LP-WUS / WUR

[0073] Considering further energy-saving processing of terminals, some research topics (such as the 3rd generation partnership project (3GPP) R18) introduced LP-WUR and designed corresponding LP-WUS signals. Specifically, when using LP-WUR to monitor the wake-up signal, the MR can be in an extremely low power state (such as ultra deep sleep state), thereby achieving energy saving of the entire terminal. LP-WUR can monitor the LP-WUS signal, and when it receives the LP-WUS signal from the network device, LP-WUR can wake up the main receiver.

[0074] The following uses the research of LP-WUS / WUR by the 3GPP RAN1 working group as an example for explanation.

[0075] When studying LP-WUS / WUR, the RAN1 working group reached a preliminary consensus on the accuracy of the LP-WUR oscillator, considering the following four options.

[0076] Option 1: The maximum frequency error of the oscillator is 200ppm, and the frequency drift of the oscillator is 0.1ppm / s.

[0077] Option 2: The maximum frequency error of the oscillator is 50ppm, and the frequency drift of the oscillator is 0.1ppm / s.

[0078] Option 3: The maximum frequency error of the oscillator is 10ppm, and the frequency drift of the oscillator is 0.05ppm / s.

[0079] Option 4: The maximum oscillator frequency error is 5ppm, and the oscillator frequency drift is 0.05ppm / s.

[0080] Consider that the maximum frequency error of the LP-WUR real-time clock (RTC) is 20ppm, and the frequency drift is 0.1ppm / s.

[0081] LP-WUS / WUR was studied in 3GPP Release 18 and published in the research report TR 38.869. LP-WUS / WUR was standardized in 3GPP Release 19. The following describes some of the standardization content and objectives in Release 19.

[0082] R19 standardizes a universal design of LP-WUS that can be applied to both IDLE / INACTIVE and CONNECTED states (RAN1, RAN4). Among them, the standardization is based on OOK (OOK-1 and / or OOK-4) LP-WUS signals, and orthogonal frequency division multiplexing (OFDM) sequences can be superimposed on the OOK symbols. The design of LP-WUS should ensure that in the IDLE / INACTIVE state, regardless of the receiver design used by LP-WUS, LP-WUS transmits the same information. At the same time, OFDM sequences can also carry information. LP-WUS can at least support duty-cycled monitoring mode.

[0083] First, for the IDLE / INACTIVE state, the process and configuration of LP-WUS triggering monitoring of paging messages are standardized, including at least: "configuration", "subgroup" and "conditions for entering / exiting LP-WUS monitoring" (RAN2, RAN1, RAN3, RAN4).

[0084] In addition, for the IDLE / INACTIVE state, an LP-SS with an LP-WUR standardized period of Yms can be used for serving cell synchronization and / or radio resource management (RRM) measurements (RAN1, RAN4). The LP-SS can be based on OOK-1 and / or OOK-4 waveforms, and may or may not superimpose an OFDM sequence on the OOK symbols. Whether or not to superimpose the OFDM sequence on the LP-SS is selected in the WI.

[0085] It should be noted that for LP-WUR that can receive the primary synchronization signal (PSS) / secondary synchronization signal (SSS) in the related technology, the PSS / SSS signal in the related technology can be used instead of LP-SS for synchronization and RRM measurement.

[0086] It should be noted that the value of Y needs to be determined in the WI phase. For example, 320m can be used as an initial value of Y.

[0087] Further standardization of RRM relaxation is carried out for the terminal's primary receiver measurements in the serving cell and neighboring cells. The RRM measurements of the terminal device's serving cell can be transferred from the MR to the LP-WUR, including the necessary condition design (RAN4, RAN2).

[0088] Secondly, for the CONNECTED state, it is necessary to standardize the process of LP-WUS triggering the terminal's primary receiver to monitor the PDCCH, including the LP-WUS activation and deactivation process (RAN2, RAN1).

[0089] It should be noted that in the CONNECTED state, the terminal's main receiver will not enter the ultra-deep sleep state, and the terminal's radio resources (RR) / radio link monitoring (RLM) / bidirectional forwarding detection (BFD) / channel state information (CSI) measurements are performed by the main receiver.

[0090] It should be noted that the coverage performance of LP-WUS and LP-SS may be close to the coverage performance of physical uplink shared channel (PUSCH) message 3 (msg3).

[0091] SSB

[0092] The following describes SSB using the NR system as an example.

[0093] Structure of SSB

[0094] In the NR system, downlink synchronization is achieved by receiving the PSS and SSS signals in the SSB. Figure 3 shows an example of the SSB structure.

[0095] In the time domain, one SSB can occupy four OFDM symbols.

[0096] In the frequency domain, 1 SSB can occupy 20 RBs.

[0097] As shown in Figure 3, the subcarriers are numbered from 0 to 239. The PSS is located on the middle 127 subcarriers (SC) of symbol #0, and the SSS is located on the middle 127 SCs of symbol #2. To protect the PSS and SSS, multiple subcarriers are set to 0.

[0098] As shown in Figure 3, in SSB, the physical broadcast channel (PBCH) can occupy all of symbols #1 and #3, as well as symbol #2 after deducting the SSS and guard band. After deducting the demodulation reference symbol (DMRS) in symbols #1 and #3, the remaining 2*(240-60)=360 subcarriers are used for PBCH transmission. After deducting the DMRS in symbol #2, the number of SCs is (240-127-8-9)*3 / 4=72. Therefore, the PBCH has a total of 432 subcarriers.

[0099] As shown in FIG3 , DMRS is inserted into PBCH for transmission, and its starting position in SSB is determined by physical cell ID modulo 4.

[0100] SSB transmission

[0101] SSB can send the same SSB in different directions using beamforming in a TDD manner, so that terminal devices in all directions can receive the SSB. The series of SSBs sent by a network device is called a synchronized broadcast block burst set (SS BURST SET).

[0102] Figure 4A illustrates an example of an SSB transmission scenario. As shown in Figure 4A , within a 5ms half-frame, the network device transmits eight SSBs with SSB indices #0 to #7 via eight beams, covering different directions. As shown in Figure 4A , these eight SSBs form a synchronized broadcast block set.

[0103] A terminal device may receive multiple SSBs with different signal strengths. The terminal device may select the beam corresponding to the SSB with the strongest signal strength among the received SSBs as its own SSB beam.

[0104] As shown in Figure 4A, UE1 and UE2 receive eight SSBs with varying signal strengths. Among the SSBs received by UE1, SSB#1 has the strongest signal strength. Therefore, the beam corresponding to SSB#1 can be used as UE1's SSB beam. Among the SSBs received by UE2, SSB#6 has the strongest signal strength. Therefore, the beam corresponding to SSB#6 can be used as UE2's SSB beam.

[0105] The period of the synchronous broadcast block set may refer to the time interval at which the synchronous broadcast block set recurs. For example, the period may default to 20ms. In the scenario shown in FIG4A , the period of the synchronous broadcast block set is 20ms. In the ServingCellConfigCommon information element (IE) of TS38.331, it can be seen that the period value range of SSB (ssb-periodicityServingCell) is ENUMERATED {ms5, ms10, ms20, ms40, ms80, ms160, spare2, spare1}.

[0106] Within 5ms, the configuration of SSB in the time domain can be shown in Table 1. Table 1 shows the starting OFDM position of SSB within 5ms.

[0107] Table 1

[0108] FIG4B is an example diagram of SSB distribution when f≤3 GHz for Case A. In FIG4B , the SSB period is 20 ms.

[0109] It should be noted that not all SSBs must be sent within a sync broadcast block set.

[0110] Exemplarily, in the ServingCellConfigCommon IE of TS38.331, the index of the actually transmitted SSB is identified by the ssb-PositionsInBurst IE. An example of the ServingCellConfigCommon IE is shown below.

[0111] Among them, shortBitmap, mediumBitmap, and longBitmap can respectively identify the index of the actually transmitted SSB in the cases of f < 3 GHz, 3 GHz < f < 6 GHz, and f > 6 GHz. shortBitmap, mediumBitmap, and longBitmap use the form of a bitmap to identify whether the corresponding SSB index is transmitted. For example, 0 can indicate not transmitted, and 1 can indicate transmitted.

[0112] FIG. 6 is a schematic flowchart of a wireless communication method provided by an embodiment of the present application. The method shown in FIG. 6 can be executed by a terminal device and a network device. The method shown in FIG. 6 can include step S610.

[0113] Step S610, a first receiver of the terminal device listens for a first signal on a first resource.

[0114] The first signal can be used to wake up a second receiver. Exemplarily, the first receiver can determine whether to wake up the second receiver according to the indication of the first signal. For example, in response to the first receiver receiving the first signal, the first receiver can wake up the second receiver. Also, in the case where the first receiver does not receive the first signal, the first receiver can not wake up the second receiver, that is, does not change the working state of the second receiver. Also, in response to the first receiver receiving the first signal and the first signal indicating to wake up the second receiver, the first receiver can wake up the second receiver. Also, in the case where the first receiver receives the first signal and the first signal indicates not to wake up the second receiver, the first receiver can not wake up the second receiver. ]>

[0115] The first signal can be sent to the terminal device or to a terminal device group where the terminal device is located. In other words, the first receiver of the terminal device can receive the first signal sent to the terminal device or the first signal sent to the terminal device group where the terminal device is located, so as to wake up the second receiver based on the first signal.

[0116] The first receiver can continuously listen for the first signal. Or, the first receiver can perform non-continuous listening for the first signal. Non-continuous listening can be performed, for example, in a duty-cycled manner.

[0117] While the first receiver is monitoring the first signal, the second receiver may be in a low-power state. A low-power state may be, for example, an ultra-deep sleep state. It is understood that in a low-power state, the second receiver may shut down or reduce some functions (e.g., not receive some or all signals) to achieve reduced power consumption. When the first receiver wakes up the second receiver, the second receiver may return to a working state. In the working state, the second receiver may turn on or resume some or all functions (e.g., receive some or all signals) to achieve normal communication.

[0118] For example, the first receiver may include a low power receiver (LR). The LR may be, for example, an LP-WUR. The second receiver may include an MR.

[0119] The first signal may include LP-WUS. The description of LP-WUS is as above.

[0120] In some embodiments, the first signal may be modulated using an OOK scheme. For example, the first signal may be based on an OOK-1 and / or OOK-4 waveform. An OFDM sequence may or may not be superimposed on the OOK symbol.

[0121] 5A and 5B respectively illustrate waveform examples of OOK-1 and OOK-4, taking the first signal including LP-WUS as an example.

[0122] As shown in Figure 5A, in the OOK-1 waveform, each OFDM symbol can transmit 1 bit of information. In other words, the time domain length of 1 OFDM can transmit 1 OOK symbol. The sub-carrier (SC) setting of the LP-WUS signal can meet the following requirements: OOK = "1": modulation is performed on all LP-WUS sub-carriers to transmit bit "1" information, and the corresponding symbol can also be called an "OOK-on" symbol; OOK = "0": the power of all LP-WUS sub-carriers is set to 0 to transmit bit "0" information, and the corresponding symbol can also be called an "OOK-off" symbol.

[0123] As shown in FIG5B , in the OOK-4 waveform, each OFDM symbol transmits M bits of information, meaning that the time domain length of one OFDM symbol transmits M OOK symbols. M can be a positive integer. For example, in FIG5B , M can be 4 bits. The value of M can be, for example, 1001.

[0124] In Figure 5B, N SCs of OOK-4are generated by a transformation (DFT / Least square). N' samples are generated from M-bits. Signal modification may or may NOT be used. Truncation or other additional modification may or may NOT be used, if not used, N is the same as N'; N' can be the same as K. K can be the total number of subcarriers.

[0125] The first resource can be used to transmit the first signal. In other words, if the first signal needs to be transmitted, the first signal can be carried on the first resource.

[0126] In some embodiments, the method shown in FIG6 may further include step S620, where the network device may send a first signal to a first receiver of the terminal device, wherein the first signal may be transmitted on a first resource.

[0127] It should be noted that the present application does not limit the order of executing step S610 and step S620. For example, step S610 and step S620 can be executed simultaneously.

[0128] It can be seen that the first resource may carry the first signal or may not carry the first signal. Therefore, the first receiver of the terminal device may receive the first signal on the first resource or may not receive the first signal.

[0129] The first resource can satisfy the first rule. For the terminal device, the terminal device can determine the first resource based on the first rule, thereby monitoring the first signal on a suitable resource, so as to accurately receive the first signal sent by the network device. For the network device, the network device can determine the first resource based on the first rule, thereby sending the first signal on a suitable resource, so that the terminal device can accurately receive the first signal.

[0130] In some embodiments, the first rule may be associated with a second resource. For ease of understanding, the second resource will be described below.

[0131] The first receiver may monitor the synchronization signal on the second resource. In other words, the second resource can be used to transmit the synchronization signal.

[0132] Optionally, the first receiver of the terminal device can be synchronized based on the synchronization signal. Due to the accuracy of the oscillator of the first receiver itself, time-frequency deviation may occur as the first signal is monitored. Therefore, by monitoring the synchronization signal, the time-frequency deviation can be eliminated.

[0133] Optionally, the terminal device may implement measurements via synchronization signals. The measurements may include RRM measurements, for example.

[0134] The first receiver may monitor the synchronization signal before monitoring the first signal. For example, after the first receiver monitors the synchronization signal for synchronization and / or RRM measurements, the first receiver may monitor the first signal. It will be appreciated that by achieving synchronization through monitoring the synchronization signal, time-frequency deviations may be eliminated, allowing the first receiver to accurately monitor the first signal and thereby wake up the second receiver at an appropriate time.

[0135] In some embodiments, the synchronization signal may be modulated using OOK. For example, the synchronization signal may be based on an OOK-1 and / or OOK-4 waveform. An OFDM sequence may or may not be superimposed on the OOK symbol.

[0136] In some embodiments, the synchronization signal may include LP-SS. For example, when the first receiver includes LR, the synchronization signal may include LP-SS. LP-SS is described above in detail.

[0137] In some embodiments, the synchronization signal may include one or more of the following: PSS, SSS, and SSB. The modulation scheme of PSS / SSS differs from that of LP-SS. For example, some high-capability LRs may be capable of monitoring one or more of PSS, SSS, and SSB. If the first receiver includes a high-capability LR, the synchronization signal may include one or more of the following: PSS, SSS, SSB, and LP-SS.

[0138] Exemplarily, LRs may have different designs. There may be at least two categories of LR receiver designs. Category 1 LRs can only accept LP-SS for synchronization and / or measurement, and do not have the ability to receive and detect one or more of PSS, SSS, and SSB. Category 2 LRs have the ability to receive and detect one or more of PSS, SSS, and SSB, that is, they can perform synchronization and / or measurement by receiving one or more of PSS, SSS, and SSB. In the case where the first receiver includes a category 1 LR, the synchronization signal monitored by the first receiver may include LP-SS. In the case where the first receiver includes a category 2 LR, the synchronization signal monitored by the first receiver may include one or more of the following: PSS, SSS, SSB, and LP-SS.

[0139] The first rule related to the second resource is described below.

[0140] In some embodiments, the first resource may include a first frequency domain resource. The second resource may include a second frequency domain resource. The first frequency domain resource and the second frequency domain resource may satisfy a first rule. In other words, the first rule may be related to the first frequency domain resource and the second frequency domain resource. For example, the second frequency domain resource may be determined based on the first rule and the first frequency domain resource. For another example, the first frequency domain resource may be determined based on the first rule and the second frequency domain resource.

[0141] As a possible implementation manner, the first frequency domain resource and the second frequency domain resource may be located in the same frequency domain resource set.

[0142] Exemplarily, the frequency domain resource set may include a bandwidth part (BWP). In this case, the first frequency domain resource and the second frequency domain resource may be located in the same BWP. Alternatively, the frequency domain resource set may include frequency domain resources actually used by the signal. In this case, the same frequency domain resource set may include frequency domain resources that do not include a guard interval in the BWP to which the first resource belongs, or frequency domain resources actually used by the first signal / synchronization signal in the BWP.

[0143] It should be noted that when the first frequency domain resource and the second frequency domain resource are located in the same frequency domain resource set, the same frequency domain resource set may be configured by the network device. In addition, the same frequency domain resource set may be a dedicated frequency domain resource set allocated for monitoring by the first receiver.

[0144] Figure 7 shows an example diagram of multiple frequency domain resource sets. In Figure 7, the first signal is an LP-WUS, the synchronization signal is an LP-SS, and the frequency domain resource set is a downlink (DL) BWP. Both the first frequency domain resource and the second frequency domain resource can be located in the DL BWP.

[0145] As shown in FIG7 , in (b), the DL BWP may include a candidate frequency domain resource set of the LP-WUS.

[0146] As shown in Figure 7, a DL BWP can include one or more LP-SS candidate frequency domain resource sets. In (c-1) or (c-2), the DL BWP includes one LP-SS candidate resource set. In (c-3), the DL BWP includes three LP-SS candidate frequency domain resource sets.

[0147] It is understandable that when the first frequency domain resource set and the second frequency domain resource set are located in the same frequency domain resource set, the same frequency domain resource set can be shared by the first signal and the synchronization signal. That is, the first signal and the synchronization signal can both be carried by the same frequency domain resource set.

[0148] Optionally, the same frequency domain resource set may include a guard interval. The guard interval cannot be used to carry the first signal and / or synchronization signal. Alternatively, the guard interval cannot be used to carry any valid signal. The guard interval may be used to separate the frequency domain resources carrying the first signal and / or synchronization signal from other frequency domain resources. The guard intervals may be distributed on both sides of the frequency domain resource set. Continuing with FIG. 7 , it can be seen that the DL BWP may include guard intervals on both sides.

[0149] Optionally, the same frequency domain resource set may be an OOK modulation dedicated frequency domain resource set. The OOK modulation dedicated frequency domain resource set may include an OOK modulation bandwidth and guard intervals evenly distributed on both sides.

[0150] In some embodiments, the frequency domain resource set used to transmit the first signal and / or synchronization signal needs to include a guard interval. For example, when the first signal is OOK modulated, the BWP used to transmit the first signal needs to include a guard interval. For another example, when the synchronization signal is OOK modulated, the BWP used to transmit the synchronization signal needs to include a guard interval. If both the frequency domain resource set used to transmit the first signal and the frequency domain resource set used to transmit the synchronization signal need to include a guard interval, the first frequency domain resource corresponding to the first signal and the second frequency domain resource corresponding to the synchronization signal are located in the same frequency domain resource set, thereby reducing the number of guard intervals required. For example, if guard intervals are included on both sides of a frequency domain resource set, if the first and second frequency domain resources are located in two different frequency domain resource sets, guard intervals need to be set on both sides of each of these two frequency domain resource sets, for a total of four guard intervals. If the first and second frequency domain resources are located in the same frequency domain resource set, guard intervals only need to be set on both sides of the same frequency domain resource set, thereby reducing the total number of guard intervals and conserving frequency domain resources, allowing more frequency domain resources to be used for transmitting valid signals.

[0151] Optionally, when the first frequency domain resource and the second frequency domain resource are located in the same frequency domain resource set, the first rule may include: the size of the first frequency domain resource and the size of the second frequency domain resource are the same, and the position of the first frequency domain resource and the position of the second frequency domain resource are the same. In other words, the first frequency domain resource and the second frequency domain resource are exactly the same. That is, the first signal and the synchronization signal use exactly the same frequency domain resource. Continuing to refer to Figure 7, the second frequency domain resource shown in (c-2) (the frequency domain resource carrying LP-SS) and the first frequency domain resource shown in (b) (the frequency domain resource carrying LP-WUS) are exactly the same in the frequency domain.

[0152] Optionally, when the first frequency domain resource and the second frequency domain resource are located in the same frequency domain resource set, the first rule may include: the center of the first frequency domain resource (i.e., the center frequency) is aligned with (or the same as) the center of the second frequency domain resource, and the size of the first frequency domain resource is different from the size of the second frequency domain resource. Exemplarily, the first frequency domain resource may be larger than the second frequency domain resource. Continuing to refer to Figure 7, the second frequency domain resource shown in (c-1) (the frequency domain resource carrying LP-SS) is smaller than the first frequency domain resource shown in (b) (the frequency domain resource carrying LP-WUS), and the centers of the second frequency domain resource shown in (c-1) and the first frequency domain resource shown in (b) are aligned.

[0153] Optionally, when the first frequency domain resource and the second frequency domain resource are located in the same frequency domain resource set, the first rule may include: the center of the first frequency domain resource and the center of the second frequency domain resource may not be aligned.

[0154] In some embodiments, the second frequency domain resource may belong to one or more of multiple candidate synchronization signal frequency domain resources in the same frequency domain resource set, and the multiple candidate synchronization signal frequency domain resources satisfy one of the following: the multiple candidate synchronization signal frequency domain resources do not overlap with each other; the multiple candidate synchronization signal frequency domain resources can overlap with each other; the centers of some or all of the multiple candidate synchronization signal frequency domain resources are aligned with the center of the first frequency domain resource.

[0155] It should be noted that any one of the multiple candidate synchronization signal frequency domain resources may be smaller than the first frequency domain resource.

[0156] It should be noted that the overlapping or non-overlapping of multiple candidate synchronization signal frequency domain resources is for the frequency domain, and there is no restriction on the overlapping in the time domain. Multiple candidate synchronization signal frequency domain resources may include a first candidate frequency domain resource and a second candidate frequency domain resource. The overlapping of the first candidate frequency domain resource and the second candidate frequency domain resource may include: in the frequency domain, the first candidate frequency domain resource and the second candidate frequency domain resource overlap; in the time domain, the first candidate frequency domain resource and the second candidate frequency domain resource may overlap or not overlap. The non-overlapping of the first candidate frequency domain resource and the second candidate frequency domain resource may include: in the frequency domain, the first candidate frequency domain resource and the second candidate frequency domain resource do not overlap; in the time domain, the first candidate frequency domain resource and the second candidate frequency domain resource may overlap or not overlap.

[0157] It should be noted that the overlap of the first candidate frequency domain resources and the second candidate frequency domain resources may mean that part or all of the frequency domain resources of the first candidate frequency domain resources and part or all of the frequency domain resources of the second candidate frequency domain resources are the same. The non-overlap of the first candidate frequency domain resources and the second candidate frequency domain resources may mean that any frequency domain resource in the first candidate frequency domain resources and the frequency domain resources of the second candidate frequency domain resources are different.

[0158] It should be noted that, the multiple candidate synchronization signal frequency domain resources do not overlap with each other may include: any two of the multiple candidate synchronization signal frequency domain resources do not overlap in the frequency domain. For example, the multiple candidate synchronization signal frequency domain resources can overlap with each other may include: any two of the multiple candidate synchronization signal frequency domain resources may not overlap in the frequency domain, or may overlap.

[0159] It should be noted that, when the synchronization signal includes LP-SS, the candidate synchronization signal frequency domain resources may also be referred to as a candidate frequency domain resource set of LP-SS.

[0160] Continuing with Figure 7, in (c-2), the DL BWP includes three LP-SS candidate frequency-domain resource sets. The center frequencies of these three LP-SS candidate frequency-domain resource sets are not aligned. Furthermore, in the frequency domain, these three LP-SS candidate frequency-domain resource sets overlap. Compared to (b), the center frequencies of two of the three LP-SS candidate frequency-domain resource sets are not aligned with the center frequency of the LP-WUS candidate frequency-domain resource set.

[0161] In some embodiments, the synchronization signal may be transmitted in a frequency hopping manner.

[0162] In some embodiments, the first frequency domain resource may be located in a first frequency domain resource set, and the second frequency domain resource may be located in a second frequency domain resource set. For example, when the synchronization signal includes PSS / SSS / SSB, the first frequency domain resource may be located in the first frequency domain resource set, and the second frequency domain resource may be located in the second frequency domain resource set.

[0163] In an optional implementation, the network device may be configured with a first frequency domain resource set and a second frequency domain resource set respectively. The first frequency domain resource set and the second frequency domain resource set configured by the network device may satisfy the first rule.

[0164] The first frequency domain resource set may include a guard interval. The guard interval may be distributed on both sides of the first frequency domain resource set. The detailed description of the guard interval is as described above and will not be repeated here.

[0165] The first set of frequency domain resources may include an OOK modulation bandwidth, that is, a bandwidth occupied by an OOK modulated signal. A guard interval may be located on both sides outside the OOK modulation bandwidth to separate the OOK modulated signal from other frequency domain resources.

[0166] As described above, a frequency domain resource set may include a BWP. Based on this, the first frequency domain resource set may be the BWP to which the first resource belongs, and the second frequency domain resource set may be the BWP to which the second resource belongs. Alternatively, the frequency domain resource set may include frequency domain resources actually used by the signal. For example, the first frequency domain resource set may be the frequency domain resources that do not include a guard interval within the BWP to which the first resource belongs. The second frequency domain resource set may be the frequency domain resources actually used by the synchronization signal. For example, if the synchronization signal includes SSBs, the second frequency domain resource set may be 20 PRBs.

[0167] In an optional implementation, the first rule may include: the first frequency domain resource set and the second frequency domain resource set may have an association relationship. For example, the network device may be configured with the first frequency domain resource set (the second frequency domain resource set may not be configured). Based on the first frequency domain resource set and the association relationship, the second frequency domain resource set may be determined. For another example, the network device may be configured with the second frequency domain resource set (the first frequency domain resource set may not be configured). Based on the second frequency domain resource set and the association relationship, the first frequency domain resource set may be determined.

[0168] In some embodiments, the association between the first frequency domain resource set and the second frequency domain resource set can be represented by the frequency domain interval (or frequency domain offset) between the two. For example, the position of the first frequency domain resource set can be determined by the following information: the position of the second frequency domain resource set; and the frequency domain interval between the first frequency domain resource set and the second frequency domain resource set. For another example, the position of the second frequency domain resource set can be determined by the following information: the position of the first frequency domain resource set; and the frequency domain interval between the second frequency domain resource set and the second frequency domain resource set.

[0169] In some embodiments, the frequency domain interval can be: the interval between the starting frequency of the first frequency domain resource set and the starting frequency of the second frequency domain resource set; the interval between the center frequency of the first frequency domain resource set and the center frequency of the second frequency domain resource set; or the interval between the ending frequency of the first frequency domain resource set and the ending frequency of the second frequency domain resource set. In other words, the reference point for calculating the frequency domain interval can be the starting frequency, the center frequency, or the ending frequency.

[0170] It should be noted that the association relationship between the first frequency domain resource set and the second frequency domain resource set may satisfy one or more of the following: predefined, or configured by a network device. For example, the frequency domain interval between the first frequency domain resource set and the second frequency domain resource set may satisfy one or more of the following: predefined, or configured by a network device.

[0171] It should be noted that the first frequency domain resource set may be different from or the same as the second frequency domain resource set. In the case where the first frequency domain resource set and the second frequency domain resource set are associated, whether the first frequency domain resource set and the second frequency domain resource set are the same can be determined based on the association.

[0172] In some embodiments, the first rule may include: the frequency domain interval between the first frequency domain resource set and the second frequency domain resource set is less than or equal to a first threshold. The first threshold may be greater than or equal to 0. The frequency domain interval may be represented by ΔF, and the first threshold may be represented by ΔF. max For example, when a network device is configured with a first frequency domain resource set and a second frequency domain resource set, the frequency domain interval between the first frequency domain resource set and the second frequency domain resource set configured by the network device is less than or equal to a first threshold. For another example, when the first frequency domain resource set and the second frequency domain resource set are associated, the frequency domain interval between the first frequency domain resource set and the second frequency domain resource set needs to be less than or equal to the first threshold.

[0173] When the frequency domain interval between the first frequency domain resource set and the second frequency domain resource set is less than or equal to the first threshold, the terminal device can more accurately obtain synchronization of the first signal by monitoring the synchronization signal.

[0174] Figure 8 is a schematic diagram of a first frequency domain resource set and a second frequency domain resource set provided in an embodiment of the present application. In Figure 8, the first signal may include LP-WUS, and the synchronization signal may include SSB. The first frequency domain resource set may be the BWP of LP-WUS; the second frequency domain resource set may be the BWP of SSB. Reference point A1 may be the starting frequency of the BWP of SSB. Reference point A2 may be the center frequency of the BWP of SSB. Reference point A3 may be the ending frequency of the BWP of SSB. Reference point B1 may be the starting frequency of the BWP of LP-WUS. Reference point B2 may be the center frequency of the BWP of LP-WUS. Reference point B3 may be the ending frequency of the BWP of LP-WUS. The frequency domain interval may be the interval between reference point A1 and reference point B1; or, the frequency domain interval may be the interval between reference point A2 and reference point B2; or, the frequency domain interval may be the interval between reference point A3 and reference point B3. In addition, as shown in Figure 8, the frequency domain interval ΔF is less than the first threshold ΔF max .

[0175] FIG8 illustrates the synchronization signal as SSB. FIG9 illustrates the synchronization signal as SSB and LP-SS. As shown in FIG9, the frequency domain interval between the BWP of SSB and the BWP of LP-WUS can be ΔF1. The frequency domain interval between the BWP of LP-SS and the BWP of LP-WUS can be ΔF2. ΔF1<ΔF max ΔF2<ΔF max .

[0176] In some embodiments, the first frequency domain resources may belong to the first allocated resources. The first allocated resources may be the total frequency domain resources indicated or allocated by the network device for the first signal. The first allocated resources may include first transmission frequency domain resources that can be occupied by the first signal and first protection frequency domain resources occupied by the guard interval. Taking the first signal as an example of OOK modulation, the first allocated resources may be frequency domain resources for transmitting the OOK signal; the first protection frequency domain resources may be frequency domain resources that cannot be occupied by the OOK signal.

[0177] Optionally, the first allocated resources may satisfy: first allocated resources=first transmission frequency domain resources+first protection frequency domain resources.

[0178] The information of the first allocated resources may include one or more of the following: the size of the first allocated resources, the location of the first allocated resources, the ratio of the first transmission frequency domain resources to the first allocated resources; the ratio of the first transmission frequency domain resources to the first protection frequency domain resources; the ratio of the first protection frequency domain resources to the first allocated resources; the size of the first transmission frequency domain resources; the location of the first transmission frequency domain resources; the size of the first protection frequency domain resources; the location of the first protection frequency domain resources.

[0179] It should be noted that the location of the frequency domain resource can be represented by one or more of the following information of the frequency domain resource: a center frequency, a start frequency, and an end frequency.

[0180] For the first protection frequency domain resource, the first protection frequency domain resource can be represented by a bilateral guard interval, or can be represented by a unilateral guard interval. The unilateral guard interval can be a guard interval at a higher position or a guard interval at a lower position among the bilateral guard intervals. Based on this, the information of the first allocated resource can be related to the unilateral guard interval and / or the bilateral guard interval.

[0181] For example, the ratio of the first transmission frequency domain resources to the first protection frequency domain resources may include one or more of the following: the ratio of the first transmission frequency domain resources to the frequency domain resources occupied by the protection interval on one side; the ratio of the first transmission frequency domain resources to the frequency domain resources occupied by the protection interval on both sides.

[0182] For example, the ratio of the first protection frequency domain resources and the first allocated resources may include one or more of the following: the ratio of the frequency domain resources occupied by the protection interval on one side to the first allocated resources; the ratio of the frequency domain resources occupied by the protection interval on both sides to the first allocated resources.

[0183] For another example, the size of the first protection frequency domain resource may include one or more of the following: the size of the frequency domain resource occupied by the protection interval on one side; the size of the frequency domain resource occupied by the protection interval on both sides.

[0184] For another example, the position of the first protection frequency domain resource may include one or more of the following: the position of the frequency domain resource occupied by the protection interval on one side; the position of the frequency domain resource occupied by the protection interval on both sides.

[0185] The information of the first allocated resource satisfies one or more of the following: predefined, configured by the network device.

[0186] For example, part of the information of the first allocated resource is predefined, and the other part is configured by the network device. Exemplarily, the position of the first transmission frequency domain resource and the position of the first protection frequency domain resource can be predefined. For example, it can be predefined that the first transmission frequency domain resource is located in the middle, and the position of the first protection frequency domain resource can be located on both sides. Exemplarily, one or more of the following can be configured by the network device: the ratio of the first transmission frequency domain resource to the first allocated resource; the ratio of the first transmission frequency domain resource to the first protection frequency domain resource; the ratio of the first protection frequency domain resource to the first allocated resource.

[0187] In some embodiments, the network device may first indicate the size and position of the first allocated resource. Further, the network device may indicate information related to the first transmission frequency domain resource in the information of the first allocated resource. The information related to the first transmission frequency domain resource may include one or more of the following: the size of the first transmission frequency domain resource, the position of the first transmission frequency domain resource, the ratio of the first transmission resource to the first allocated resource, etc. Further, the network device may indicate information related to the first protection frequency domain resource. The information related to the first protection frequency domain resource may include one or more of the following: the size of the first protection frequency domain resource, the position of the first protection frequency domain resource, the ratio of the first protection frequency domain resource to the first allocated resource, and the ratio of the first transmission frequency domain resource to the first protection frequency domain resource.

[0188] In some embodiments, the network device may first indicate information related to the first transmission frequency domain resource and may not indicate information related to the first protection frequency domain resource. Optionally, when transmitting the first signal, the network device may determine the size of the guard intervals on both sides according to a predefined method. Alternatively, the network device may further indicate information related to the first protection frequency domain resource.

[0189] In some embodiments, the second frequency domain resources may belong to the second allocated resources. The second allocated resources may be the total frequency domain resources indicated or allocated by the network device for the synchronization signal. The second allocated resources may include the second transmission frequency domain resources that can be occupied by the synchronization signal and the second protection frequency domain resources occupied by the guard interval. Taking the synchronization signal as an example of OOK modulation, the second allocated resources may be the frequency domain resources transmitted by the OOK signal; the second protection frequency domain resources may be the frequency domain resources that cannot be occupied by the OOK signal.

[0190] Optionally, the second allocated resources may satisfy: second allocated resources=second transmission frequency domain resources+second protection frequency domain resources.

[0191] The information of the second allocated resources may include one or more of the following: the size of the second allocated resources, the location of the second allocated resources, the ratio of the second transmission frequency domain resources to the second allocated resources; the ratio of the second transmission frequency domain resources to the second protection frequency domain resources; the ratio of the second protection frequency domain resources to the second allocated resources; the size of the second transmission frequency domain resources; the location of the second transmission frequency domain resources; the size of the second protection frequency domain resources; and the location of the second protection frequency domain resources.

[0192] For the second protection frequency domain resources, the second protection frequency domain resources can be represented by bilateral guard intervals, or can be represented by unilateral guard intervals. The unilateral guard interval can be a guard interval at a higher position or a guard interval at a lower position among the bilateral guard intervals. Based on this, the information of the second allocated resources can be related to the unilateral guard interval and / or the bilateral guard interval. For example, the ratio of the second transmission frequency domain resources to the second protection frequency domain resources can include one or more of the following: the ratio of the second transmission frequency domain resources to the frequency domain resources occupied by the unilateral guard interval; the ratio of the second transmission frequency domain resources to the frequency domain resources occupied by the bilateral guard interval. For another example, the ratio of the second protection frequency domain resources to the second allocated resources can include one or more of the following: the ratio of the frequency domain resources occupied by the unilateral guard interval to the second allocated resources; the ratio of the frequency domain resources occupied by the bilateral guard interval to the second allocated resources. For another example, the size of the second protection frequency domain resources can include one or more of the following: the size of the frequency domain resources occupied by the unilateral guard interval; the size of the frequency domain resources occupied by the bilateral guard interval. For another example, the position of the second protection frequency domain resource may include one or more of the following: the position of the frequency domain resource occupied by the guard interval on one side; the position of the frequency domain resource occupied by the guard interval on both sides.

[0193] The information of the second allocated resources satisfies one or more of the following: predefined, configured by the network device. For example, part of the information of the second allocated resources is predefined, and the other part is configured by the network device. Exemplarily, the position of the second transmission frequency domain resource and the position of the second protection frequency domain resource can be predefined. For example, it can be predefined that the second transmission frequency domain resource is located in the middle, and the position of the second protection frequency domain resource can be located on both sides. Exemplarily, one or more of the following can be configured by the network device: the ratio of the second transmission frequency domain resource to the second allocated resource; the ratio of the second transmission frequency domain resource to the second protection frequency domain resource; the ratio of the second protection frequency domain resource to the second allocated resource.

[0194] In some embodiments, the network device may first indicate the size and position of the second allocated resource. The network device may further indicate information related to the second transmission frequency domain resource in the information of the second allocated resource. The information related to the second transmission frequency domain resource may include one or more of the following: the size of the second transmission frequency domain resource, the position of the second transmission frequency domain resource, and the ratio of the second transmission resource to the second allocated resource. Further, the network device may indicate information related to the second protection frequency domain resource. The information related to the second protection frequency domain resource may include one or more of the following: the size of the second protection frequency domain resource, the position of the second protection frequency domain resource, the ratio of the second protection frequency domain resource to the second allocated resource, and the ratio of the second transmission frequency domain resource to the second protection frequency domain resource.

[0195] In some embodiments, the network device may first indicate information related to the second transmission frequency domain resources and may not indicate information related to the second protection frequency domain resources. Optionally, when the network device sends the synchronization signal, the size of the guard intervals on both sides may be determined according to a predefined method. Alternatively, the network device may further indicate information related to the second protection frequency domain resources.

[0196] It should be noted that the ratio of A to B mentioned above can be A / B or B / A. That is, this application does not limit which of A and B is in the denominator.

[0197] The above describes the association relationship between the first resource and the second resource in the frequency domain. The following describes the association relationship between the first resource and the second resource in the time domain.

[0198] In some embodiments, the first resource may include a first time domain resource, and the second resource may include a second time domain resource. The first time domain resource and the second time domain resource may be associated, i.e., have an associated relationship. For example, the second time domain resource may be determined by the first time domain resource. For another example, the first time domain resource may be determined by the second time domain resource.

[0199] In some embodiments, the first time domain resource and the second time domain resource may be time-divided. That is, the first signal and the synchronization signal are sent in time division in the time domain. For example, when the first frequency domain resource and the second frequency domain resource belong to the same frequency domain resource set, the first time domain resource and the second time domain resource may be time-divided.

[0200] In some embodiments, the first time domain resource may belong to N candidate time domain resources. N may be a positive integer. The candidate time domain resource can be used to transmit the first signal. In other words, the candidate time domain resource may be a time domain monitoring resource or a transmission resource for the first signal. The terminal device may monitor the first signal on the candidate time domain resource, and the network device may transmit the first signal on the candidate time domain resource.

[0201] Exemplarily, the network device may transmit the first signal on N candidate time domain resources. For example, if it is necessary to wake up the second receiver, the network device may transmit the first signal on one or some of the N candidate time domain resources. For another example, if it is not necessary to wake up the second receiver, the network device may not transmit the first signal. Therefore, the terminal device may not receive the first signal on some candidate time domain resources.

[0202] It should be noted that N may satisfy one or more of the following: predefined, configured by network equipment, or specified by a protocol.

[0203] In some embodiments, N candidate time domain resources may be used to transmit M first signals. M may be greater than or equal to N. In other words, each candidate time domain resource may be used to transmit at least one first signal. A terminal device may monitor a first signal on a candidate time domain resource and may receive the first signal.

[0204] In some embodiments, the second time domain resource may be a periodically arranged resource. For example, the network device may configure a time domain resource for transmitting a periodic synchronization signal. The network device may transmit a synchronization signal on the periodically arranged resource. The periodic arrangement of resources may indicate that corresponding resources may appear at intervals of the same duration (i.e., period). For example, the period of the second time domain resource may be 320 ms. In other words, the network device may transmit a synchronization signal at intervals of 320 ms, and the terminal device may monitor the synchronization signal.

[0205] FIG10 is an example diagram of an arrangement of time domain resources provided by an embodiment of the present application. In FIG10 , the synchronization signal includes LP-SS, that is, the second time domain resource can be a time domain resource capable of transmitting LP-SS. As shown in FIG10 , the second time domain resource is arranged according to a period. The period is T LP-SS .

[0206] In some embodiments, the second time domain resources may be arranged according to the transmission requirements of the synchronization signal. For example, when a synchronization signal needs to be sent, the network device may schedule the time domain resources for sending the synchronization signal.

[0207] In some embodiments, the second time domain resources may be periodically arranged, and the second time domain resources may be arranged according to the transmission requirements of the synchronization signal. For example, when it is necessary to send a synchronization signal, the network device may send the synchronization signal on the periodically arranged synchronization signal transmission time domain resources; when it is not necessary to send a synchronization signal, the network device will not send the synchronization signal on the periodic synchronization signal transmission time domain resources.

[0208] The second time domain resource can be associated with N candidate time domain resources. That is, the N candidate time domain resources can be determined using the second time domain resource. Alternatively, the second time domain resource can be determined using the N candidate time domain resources. For example, the association between the second time domain resource and the N candidate time domain resources can be related to the time domain interval between the second time domain resource and the N candidate time domain resources. Based on the second time domain resource and the time domain interval, the N candidate time domain resources can be determined, thereby determining the first time domain resource.

[0209] As a possible implementation, a target time domain resource unit where the N candidate time domain resources are located may be determined. Further, a time domain resource sub-unit where the N candidate time domain resources are located may be determined in the target time domain resource unit.

[0210] For example, the target time domain resource unit may be the first time domain resource unit where the N candidate time domain resources are located. In another example, the target time domain resource unit may include any one or more time domain resource units where the N candidate time domain resources are located.

[0211] It should be noted that a time domain resource unit may include multiple time domain resource sub-units. For example, a time domain resource unit may be a frame, and a time domain resource sub-unit may be a symbol. In other words, by determining the target frame in which the N candidate time domain resources are located, the symbols occupied by the N candidate time domain resources in the target frame can be determined.

[0212] In some embodiments, the interval between the time domain resource unit where the second time domain resource is located and the target time domain resource unit may be a first time interval. The target time domain resource unit may be determined according to the first time interval.

[0213] Optionally, there may be multiple first time intervals, which may correspond one-to-one to the multiple time domain resource units where the N candidate time domain resources are located. The multiple time domain resource units where the N candidate time domain resources are located may be determined respectively according to the multiple first time intervals.

[0214] Optionally, there may be one first time interval, which may correspond to a certain time domain resource unit where the N candidate time domain resources are located. By determining the certain time domain resource unit where the N candidate time domain resources are located, all time domain resource units where the N candidate time domain resources are located may be further determined.

[0215] It should be noted that the first time interval may satisfy one or more of the following: predefined, configured by the network device.

[0216] It should be noted that, considering that the first time domain resource can be determined by the time domain resource unit where the second time domain resource is located, the time domain resource unit where the second time domain resource is located can also be called a reference time domain resource unit. Taking the time domain resource unit as a frame as an example, the reference time domain resource unit can be a reference frame.

[0217] Figure 11 is an example diagram of the association between the second time domain resource and N candidate time domain resources provided in an embodiment of the present application. As shown in Figure 11, the second time domain resource can be associated with 8 candidate time domain resources, that is, N=8. The terminal device can monitor the first signal on the 8 candidate time domain resources. In the scenario shown in Figure 8, the fourth candidate time domain resource actually transmits the first signal. Therefore, the terminal device can receive the first signal on the fourth candidate time domain resource, and cannot receive the first signal on other candidate time domain resources.

[0218] In Figure 11, the first time interval is represented by a "time domain offset." The frame containing the N candidate time domain resources is called an LP-WUS frame. The first LP-WUS frame can be the target frame. The time domain position of the target frame can be determined based on the reference frame containing the second time domain resource and the time domain offset.

[0219] The time interval between the first time domain resource sub-unit of the target time domain resource unit and the time domain resource sub-unit occupied by the N candidate time domain resources in the target time domain resource unit is the second time interval. Alternatively, the index of the time domain resource sub-unit occupied by the N candidate time domain resources in the target time domain resource unit may be the second time interval. The time domain resource sub-unit occupied by the N candidate time domain resources in the second target time domain resource unit may be determined based on the second time interval.

[0220] Optionally, there may be multiple second time intervals, each corresponding to a plurality of time domain resource sub-units that can be occupied by the first signal in the target time domain resource unit. Based on the multiple second time intervals, it may be determined which time domain resource sub-units in the target time domain resource unit are to be monitored for the first signal.

[0221] Optionally, there may be one second time interval, which may correspond to the first time domain resource subunit that the first signal can occupy in the target time domain resource unit. Based on the one second time interval, the first time domain resource subunit that the first signal can occupy in the target time domain resource unit can be determined, and then other time domain resource subunits that the first signal can occupy in the target time domain resource unit can be determined.

[0222] It should be noted that the number of time domain resource sub-units that can be occupied by the first signal in the target time domain resource unit can meet one or more of the following conditions: predefined, configured by the network device. If the number of time domain resource sub-units corresponds to the monitoring opportunities of the first signal, the number of monitoring opportunities for the first signal in the target time domain resource unit can meet one or more of the following conditions: predefined, configured by the network device.

[0223] It should be noted that the second time interval may satisfy one or more of the following: predefined, configured by the network device.

[0224] In some embodiments, the time interval between the time domain resource subunit where the second time domain resource is located and the time domain resource subunits where the N candidate time domain resources are located may be a third time interval, and the time domain resource subunits where the N candidate time domain resources are located are determined based on the third time interval.

[0225] For example, the third time interval may be the interval between the first time domain resource sub-unit where the second time domain resource is located and the first time domain resource sub-unit where the N candidate time domain resources are located. For another example, the third time interval may be the interval between the last time domain resource sub-unit where the second time domain resource is located and the first time domain resource sub-unit where the N candidate time domain resources are located. For another example, the third time interval may be the interval between the first time domain resource sub-unit where the second time domain resource is located and the last time domain resource sub-unit where the N candidate time domain resources are located. For another example, the third time interval may be the interval between the last time domain resource sub-unit where the second time domain resource is located and the last time domain resource sub-unit where the N candidate time domain resources are located.

[0226] Optionally, there may be multiple third time intervals. The multiple third time intervals may correspond one-to-one to the multiple time domain resource subunits where the N candidate time domain resources are located. Based on the multiple third time intervals, the multiple time domain resource subunits where the N candidate time domain resources are located may be determined respectively.

[0227] Optionally, one third time interval may exist. The one third time interval may correspond to any one of the N candidate time domain resources. For example, any one of the time domain resource subunits may be the first one of the N candidate time domain resources. In other words, the first one of the N candidate time domain resources may be determined based on the one third time interval.

[0228] In some embodiments, when some of the N candidate time-domain resources are capable of transmitting a first signal for a terminal device, the some of the N candidate time-domain resources may be determined based on one or more of the following information: an identifier of the terminal device (UE ID); an identifier of the terminal group to which the terminal device belongs (UE group ID); and an identifier of a sub-terminal group of the terminal device (UE subgroup ID). That is, a mapping relationship may exist between the N candidate time-domain resources and each terminal device, and the mapping relationship may be determined based on the above information of the terminal device.

[0229] It is understandable that some of the N candidate time domain resources can be used to transmit a first signal for a terminal device, while another portion of the N candidate time domain resources is not used to transmit the first signal for the terminal device. For example, another portion of the candidate time domain resources can be used to transmit the first signal for other terminal devices. Based on one or more of the following: the identifier of the terminal device, the identifier of the terminal group, and the identifier of the sub-terminal group, the terminal device can determine the candidate time domain resources to be monitored, and the network device can determine the candidate time domain resources to be used to send the first signal to the terminal device.

[0230] In some embodiments, the monitoring result of the synchronization signal can be used to indicate one or more of the following information: whether the N candidate time domain resources transmitted the first signal; the candidate time domain resources that transmitted the first signal among the N candidate time domain resources; and the candidate time domain resources that did not transmit the first signal among the N candidate time domain resources. The monitoring result of the synchronization signal may include a sequence of synchronization signals. For example, the network device may indicate the above information of the first signal through the sequence of synchronization signals. For another example, the terminal device may determine the above information of the first signal through the sequence of synchronization signals.

[0231] Optionally, the synchronization signal can be associated with a terminal device. For example, the synchronization signal can be associated with the terminal device using one or more of the following information about the terminal device: the terminal device's identifier; the identifier of the terminal group to which the terminal device belongs; or the identifier of the sub-terminal group to which the terminal device belongs. The association relationship can indicate which terminal devices need to monitor the first signal associated with the synchronization signal.

[0232] In some embodiments, the time domain resource of the PO may be a third time domain resource. The first time domain resource may be associated with the third time domain resource. In other words, the first time domain resource may be determined based on the third time domain resource. A fourth time interval may exist between the third time domain resource and the first time domain resource. The first time domain resource may be determined based on the fourth time interval and the third time domain resource.

[0233] Figure 12 is an example diagram of a first signal, a synchronization signal, and the time domain resources occupied by PO provided in an embodiment of the present application. As shown in Figure 12, the first receiver monitors the periodically transmitted synchronization signal (the synchronization signal in Figure 12 includes LP-SS) to obtain the necessary synchronization and perform RRM measurements. According to the time domain resources occupied by PO and the fourth time interval T4, the first time domain resources (i.e., the resources for actually transmitting LP-WUS in Figure 12) can be determined. When the first signal is detected (the first signal in Figure 12 includes LP-WUS), the first receiver needs to wake up the second receiver to receive the paging. During T4, the second receiver wakes up from ultra-deep sleep.

[0234] In some embodiments, the fourth time interval between the time domain resource occupied by the PO and the first time domain resource may be larger than the first time interval between the second time domain resource and the first time domain resource. For example, according to 3GPP R18 research, the MR needs to undergo a ramp-up startup time and necessary synchronization to switch from an ultra-deep sleep state to a state listening for paging, which takes at least approximately 400 ms. Therefore, the time interval between the LP-WUS and the PO needs to be at least greater than 400 ms. As described above, the period of the synchronization signal (e.g., LP-SS) can be considered to be 320 ms. Therefore, the time interval from the LP-WUS to the adjacent LP-SS is relatively smaller than the time interval to the PO.

[0235] In some embodiments, the time domain resources corresponding to the first resource may be periodically arranged. Based on the periodic arrangement pattern, the network device and / or the terminal device may determine the first resource. For example, the first resource may belong to multiple wake-up frames. The wake-up frames may be periodically arranged.

[0236] Multiple periodically arranged wake-up frames may be represented by one or more of the following: a period, or one or more offsets within a period. For example, for a frame numbered nSFN, if nSFN mod x = y, the frame may be a wake-up frame. Here, x is equal to the wake-up frame period, and y is the index or offset of a time domain resource capable of transmitting the first signal within the period.

[0237] The following uses Figure 13 as an example for illustration. In Figure 13 , the wake-up frame period is represented by T. The values ​​of y are 2 and 4. As shown in Figure 13 , within the window corresponding to period T, frame #x+2 and frame #x+4 can be wake-up frames.

[0238] In some embodiments, the time domain resources available for transmitting the first signal in the wake-up frame may be indicated by the following parameter: the time domain position occupied by the time domain resources available for transmitting the first signal in the wake-up frame. For example, the time domain resources available for transmitting the first signal in the wake-up frame may be indicated by the following parameter: the symbol occupied by the time domain resources available for transmitting the first signal in the wake-up frame. In other words, the symbols available for the first signal may be directly determined in the wake-up frame.

[0239] It should be noted that the time domain position that the first signal can occupy in the wake-up frame can be predefined and / or configured by the network device. In the case of being configured by the network device, the time domain position that the first signal can occupy in the wake-up frame can be configured through RRC signaling.

[0240] The time domain position that the first signal can occupy in the wake-up frame can be determined by the symbol start position in the wake-up frame. The network device can be configured with one or more symbol start positions.

[0241] In some embodiments, the time domain resources that can be used to transmit the first signal can be determined in multiple levels. For example, the time domain resources that can be used to transmit the first signal in the wake-up frame can be indicated by the following parameters: the subframe number occupied by the time domain resources that can be used to transmit the first signal in the wake-up frame, and the symbol occupied in the subframe number. That is, one or more subframes that the first signal can occupy in the wake-up frame can be determined first, and then the one or more symbols that the first signal can occupy in the subframe can be determined. Among them, the one or more symbols that the first signal can occupy in the subframe can be indicated by the offset of the symbol in the subframe.

[0242] 13 , in the wake-up frame #x+2, it can be determined that the subframes that the first signal can occupy are subframe #3 and subframe #6. For subframe #3, it can be determined that the symbol that the first signal can occupy is the gray part.

[0243] It should be noted that the length of the time domain resources that can be occupied by the first signal can meet one or more of the following: agreed upon by the protocol, configured by the network device. The length of the time domain resources that can be occupied by the first signal can be the number of symbols. For example, the length of the time domain resources that can be occupied by the first signal can be the number of consecutive symbols.

[0244] Optionally, the determined first time domain resource may be a time domain resource corresponding to a single beam sending the first signal, and the first signal and the synchronization signal may be QCL.

[0245] Optionally, when the first signal includes an LP-WUS, the determined LP-WUS time domain resource (i.e., the first time domain resource) may be a time domain resource of an LP-WUS burst set. The LP-WUS burst set may include X LP-WUS time domain resources, where X may be the same as the number of beams used. The LP-WUS may be QCL with the synchronization signal.

[0246] As described above, the periodically arranged first time domain resources may be configured by the network device. For example, the IE in the following RRC signaling may be used to configure the periodically arranged first time domain resources.

[0247] The first information element may be used to indicate the period of the first signal. The first information element may be represented by LPWUS-periodicityServingCell.

[0248] The second information element may be used to configure the position of the wake-up frame within the period (ie, one or more offsets within a period). The second information element may be represented by LPWUS-positionInPeriodicity.

[0249] The third information element may be used to indicate the subcarrier spacing of the first signal. The third information element may be represented by LPWUS-SubcarrierSpacing.

[0250] The fourth information element may be used to indicate the length of the first time domain resource. The fourth information element may be represented by LPWUS-Duration.

[0251] The fifth information element may be used to indicate the time domain position of the first signal within the wake-up frame. The fifth information element may include one or more offsets. The fifth information element may include one or more levels of offsets. The fifth information element may be represented by LPWUS-timeoffset.
